Answer: 400

Step-by-step explanation:

If 5% of a number is 80, just multiply that number by 5 to get 25 (5 x 5 = 25) and you will get 400.

Alborosie

Answer:

y=740x-400

Step-by-step explanation:

The story tells us that Boa drove from the Dead Sea up to Jerusalem. With the data provided, we can assume a linear relationship between altitude and the number of hours. We are given two key data: one point and the rate of change (or slope).

We can easily find the equation of a line with slope m passing through a point (a,b) by using the formula

y-b=m(x-a)

In this case, y is the altitude above sea level, and x is the number of hours of driving

The value of m is 740 meters/hour and the known point is x=1.5 hours, y=710 meters. Using these values

y-710=740(x-1.5)

y-710=740x-1110

y=740x-400

I just plugged both equations into my calculator and found where they intersect. But you can do the same on paper by manually finding that intersection in the graph which should be (2,4)

Find dy/dx if. y = inverse of cos x​
nataly862011 [7]

Answer:

dy/dx = -1 /√(1 - x^2).

Step-by-step explanation:

y = arccos x.

So x  = cos y

dx / dy = - sin y

dy / dx = -1 / sin y

But sin y = √( 1 - cos^2 y)

But cos y = x , so cos^2y = x^2

Therefore  

dy/dx = -1 / √(1 - x^2).
